4731-97-9 Usage
General Description
1,1':4',1''-Terbenzen-3'-ol, also known as bisphenol A, is a synthetic compound commonly used in the production of plastic products and epoxy resins. It is known for its potential to leach into food and beverages from containers and packaging, posing potential health risks to humans. Studies have linked exposure to bisphenol A with adverse effects on the reproductive and developmental systems, as well as an increased risk of certain cancers. Due to these concerns, many manufacturers and governments have taken steps to limit or ban the use of bisphenol A in various applications, and alternatives are being sought for its widespread use.
Check Digit Verification of cas no
The CAS Registry Mumber 4731-97-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,3 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4731-97:
(6*4)+(5*7)+(4*3)+(3*1)+(2*9)+(1*7)=99
99 % 10 = 9
So 4731-97-9 is a valid CAS Registry Number.

A new cascade radical reaction for the synthesis of biaryls and triaryls from benzyl iodoaryl ethers
Harrowven, David C.,Nunn, Michael I.T.,Newman, Nicola A.,Fenwick, David R.
, p. 961 - 964 (2007/10/03)
The paper describes a new method of synthesizing biaryls and triaryls through an intramolecular ipso-substitution reaction initiated by the addition of an aryl radical to a benzyl ether. A tandem variant of the reaction has also been demonstrated. A short synthesis of isoaucuparin 27, a natural product found in the sapwood tissue of Sorbus aucuparia, is also described.
